ON SOME GENERIC NAMES FIRST MENTIONED IN THE ''CONCHOLOGICAL ILLUSTRATIONS." By William Healey Dall, Curator, Division of Mollushs, United States National Museum.. In reviewing the Fissurellidae of the Pacific coast of North America I found some confusion existing in the synonymy of several well-known species and genera, the clearing up of which may have some interest for students. The following data will serve toward that end : Genus LUCAPINA (Gray) Sowerby, 183S. Lucapina (elegans) Gray, in Sowerby, Conch. 111., FissureUa, p. 4, No. 38, fig. 29, June, 1835; as synonym of F. canceUata Sowerby, Conch. 111., p. 4 (asof Solander MS.) Lucapina Philippi, Test. Utr. Sicil., vol. 2, 1844, p. 90, cites canceUata Sowerby, as type and sole species mentioned. Lucapina (Gray) Herrmannsen, Index Gen. Mai., vol. 1, p. 627, 1846; cites Fis-sureUa canceUata as type. Lucapina Gray, Syn. (^ont. Brit. Mus., ed. 42, p. 147; nude name under Fissurellidae, no species cited; ed. 44, 1840, p. 114 (ed. 44 A., 1840, p. 117), one line of diagnosis, no species cited. Lucapina Gray, Proc. Zool. Soc, 1847, p. 147, No. 160, cites FissureUa aperta Sowerby, and L. elegans Gray. Lucapina (Gray) Herrmannsen, Index Gen. Mai., Suppl., p. 76, 1852, cites FissureUa aperta Sowerby, following Gray in Proc. Zoul. Soc, 1847. Lucapina Gray, in M. E. Gray, Fig. Moll. An., vol. 4, p. 92, 1850, cites L. canceUata and L. crenulata, nude names, as examples. Foraminella (Guilding MS.) Sowerby, Conch. 111., p. 4, No. 38, June, 1835, as Forami-nella sowerbii Guilding, MS.; St. Vincent, West Indies. This name precedes Lucapina in the text, and is cited as a synonym of FissureUa canceUata Sowerby, Conch. 111., p. 4, Foraminella Guilding, Cat. Conch. Nom., 1845, according to Agassiz in Scudder, Nomencl. Zoologicus, p. 139, 18*82.— Catlow, Conch. Nomencl., p. 102, No. 11, 1845; cites from Sowerby, Conch. 111., 1835. Not Foraminella Leven. Brach. 1902.) Lucapina H. and A. Adams, Gen. Rec. Moll., vol. 1, p. 447, 1854; examples figured L. reticulata Donovan and L. crenulata Sowerby; vol. 2, p. 630, 1858, notes segrega-tion of subgenus Glyphis Carpenter, and cites G. inaequalis as sole example, also Capiluna Gray, as synonym. Lucapina Woodward, Manual, p. 150, 1852, F. elegans Gray, sole example cited; but it is confused with F. crenulata Sowerby, from which the diagnosis is drawn. Glyphis Carpenter, Mazatlan Cat., p. 220, 1856; first species FissureUa inaequalis Sowerby. (Not Glyphis Agassiz, 1853.) Proceedings U. S. National Museum, Vol. 48— No. 2079. 437
